Auction House or Player's Store

[Fugaku]

What is the possibility of creating such a system? users can create their 'street shops' when they want to be AFK or simply want to sell their items. A command like /sellitems or something similar where then open a window to place the object to sell and its price, when placing the items for sale and pressing 'OK' an item or table is created that when interacting, opens the window with the items for sale.

It's a hard thing to make, and there are a million ways to do it. I suggest you come with a more concrete request, specifically explain how you had it in mind. 

Then all you can do is hope you get really lucky someone will make this.
